•  Data Element:

                           It is used to describe the semantic definition of the table fields like description the field. Data element describes how a field can be displayed to end-user.

A reference type defines the types of reference variables in ABAP programs.An elementary type is defined by the built-in data type, length and possibly the number of decimal places. These type attributes can either be defined directly in the data element or copied from a domain.A data element describes either an elementary type or a reference type.

The field CONNID (flight class) of table SBOOK refers to the data element S_CONN_ID. This data element gets its technical attributes (data type NUMC, field length 4) from domain S_CONN_ID. Data element S_CONN_ID describes the technical attributes and meaning (with an assigned long text and an explanatory short text) of field CONNID (and all other fields that refer to this data element).
A variable having the type of data element S_CONN_ID can be defined in an ABAP program with the statement DATA CONNID TYPE S_CONN_ID.
